Oracle 1z0-133 Exam Questions

Question 6 of 136

You configure a data source with a non XA driver because your (non-Oracle) database does not provide XA drivers.
The data source will sometimes participate in global transactions with an EJB, so as you configure the data source you select "Supports Global Transactions" and
One-phase commit.
Why is this configuration wrong?

You must choose an XA driver when a data source participates in global transactions.

"One' Phase Commit" always returns "ready" during phase one of the two-phase commit process' so it is possible you will have heuristic errors in the database.

"One-Phase Commit" processes this data source last in the global transactions, if the EJB must go last, you cannot use this configuration.

"One-Phase Commit" only allows this data source to participate in global transaction, so you cannot have a global transaction that includes an EJB.

Correct Answer: B

Selecting 'One-Phase Commit' in a global transaction allows the data source to return 'ready' during the first phase of the two-phase commit process. This can lead to potential heuristic errors in the database, which makes the configuration problematic when dealing with global transactions involving multiple resources.

Question 7 of 136

When creating a dynamic cluster, you have multiple options concerning how dynamic servers are distributed across machines in your domain. Identify three supported configurations. (Choose three.)

Use a single machine.

Use all machines in a subnet.

Use all machines in the domain.

Use all percentage of machines in the domain.

Use all machines whose names match an expression.

Correct Answer: A, C, E

Question 8 of 136

Which action should you take to automatically back up the domain configuration when anyone activates a configuration change?

USE the backup='true' parameter of the activate() command in WLST.

The administration console, select "Follow Configuration changes" in the Shared Preferences for the console.

In the administration console, select "Configuration Archive Enabled" under the general configuration of the domain.

Enabling automatic domain configuration creates backups of the configuration during server boot, not at each activation.

Correct Answer: C

To automatically back up the domain configuration when any configuration change is activated, you should select 'Configuration Archive Enabled' under the general configuration of the domain in the administration console. This action ensures that the domain configuration is archived each time a configuration change is made.

Question 9 of 136

As the technical lead for your project, you have been asked to recommend a new solution to handle frequently increasing loads on your applications. The
WebLogic 12.1.2 domain currently runs with two clusters of three servers with request being filtered and passed by a proxy server that users the round ""robin algorithm.
However, the load sometimes exceeds the maximum capacity of all these servers combined but your domain lacks in scalability.
What is the best implementation solution?

Add a third cluster and spread existing server instances across the clusters.

Modify the proxy server load balancing algorithm to weight based.

Configure dynamic clusters and specify the number of server instances you anticipate needing at peak load.

Tune work managers to optimize work.

Replace the software load balancer with a hardware load balancer.

Correct Answer: C

To handle frequently increasing loads and improve scalability, configuring dynamic clusters and specifying the number of server instances needed at peak load is the best solution. This allows the system to automatically adjust the number of server instances based on the current load, ensuring that the application can handle higher traffic without manual intervention.

Question 10 of 136

All administrators that deal with the production domain in your organization are extremely experienced. As the lead administrator, you have been asked to change the administration console preferences for all administrators so that inline help no longer displays, since no one needs it.
Select the true statement about this scenario.

There is nothing you can do, since inline help cannot be disabled.

There is nothing you can do for all users, since disabling inline help must be done per user.

Log into the administration console and disable inline help under "help."

Access WLST, connect to the domain's admin server, and use the command EnableInlineHelp (false).

Correct Answer: B

Disabling inline help must be done on a per-user basis. This means that as the lead administrator, you cannot change the setting for all administrators at once. Each administrator needs to modify their own preferences individually to disable inline help.
